A man in his 20s has been arrested by Gardaí investigating the alleged sexual assault of an 18-year-old woman who had just exited a Nitelink bus.

Gardaí from Blanchardstown are investigating the alleged incident, which occurred at approximately 4am in the Littlepace area of Dublin 15 in the early hours of the 18th of December.

While walking home she was approached, threatened and assaulted by a lone male. The woman managed to fend off her attacker and raise the alarm by flagging down a passing Taxi before alerting Gardaí. Her phone was also taken during the incident.

A man was arrested in the west Dublin area yesterday by investigating Gardaí and is currently detained under Section 4 of the Criminal Justice Act, 1984 at Blanchardstown Garda Station.
